Have you tried operating an ATM in another language?
In Singapore once at an ATM, I selected Malay as my language by mistake. Despite having used that ATM a thousand times, despite the language being readable due to the familiar script, I froze. I cancelled the transaction hurriedly and logged in again in English.
Now can you imagine having to operate an ATM when you can't read any language? Empathise empathise. Please.
